Environmental Protection Agency (EPA) Model Lead Based Paint Risk Assessor Practice Test

What must be conducted before carrying out dust clearance sampling after renovation?

1. A visual assessment of the area

2. Notification to residents

3. Re-clean and retest

4. Setup of containment barriers

The correct answer is: Re-clean and retest

Before conducting dust clearance sampling after renovation, it is essential to perform a re-clean and retest. This step ensures that any lead-based paint dust generated during the renovation process has been effectively removed from the area. Re-cleaning involves thorough cleaning of surfaces to minimize lead dust hazards, and retesting includes sampling dust to verify that levels of lead are below the acceptable thresholds established by the EPA. This process is critical for safeguarding the health of residents, especially children, who are more vulnerable to the adverse effects of lead exposure. Completing the re-clean and retest provides a clear indication of whether the area is safe for occupancy after renovations have taken place, ensuring compliance with lead safety regulations. Dust clearance sampling can only proceed once these preliminary measures demonstrate that the area meets the required safety standards.
